should law enforcement remove evidence from an accident scene without supplying a supplemental report?

Question

If a deputy assist another deputy (lead investigator) in an accident investigation, and he removes evidence (such as hair) off one of the boats, shouldn't he supply a supplemental report to the lead investigator? Why would a deputy remove evidence from the boat?

Answer 1

would they not remove evidence if they are collecting it as part of an investigation? do you think they just leave evidence once they find it, on the ground, to be blown away by wind, or hurt or washed away?

they fill out a form when they collect it and give it to whatever forensic team there, to follow the chain of custody.
